In List item click

 l1.setOnItemClickListener(new OnItemClickListener() {
               public void onItemClick(AdapterView<?> parent, View view,
                   int position, long id) {
                   // When clicked, show a toast with the TextView text
                  Toast.makeText(getApplicationContext(), "SELECTED :: " +((TextView) view).getText(), Toast.LENGTH_SHORT).show();


                  String s2=(String) ((TextView) view).getText();


                  // String ss=Integer.toString(myid);

you add values to a string array like
    String[] S5=new String[]{s2}; 
         this will ovverride the previous element the all time shall 
    not add any other value




                  //String[] S1=new String[]{s2};
                  GlobalClass.myval=S5;
                  for (int i=0;i<GlobalClass.myval.length;i++){
                      System .out.println("Clicked-->"+GlobalClass.myval[i]);
                  }

do it like this first

// declare array list before on create in your activity

    private ArrayList<String> AddedItems = new ArrayList<String>();


l1.setOnItemClickListener(new OnItemClickListener() {
       public void onItemClick(AdapterView<?> parent, View view,
           int position, long id) {
           // When clicked, show a toast with the TextView text
          Toast.makeText(getApplicationContext(), "SELECTED :: " +((TextView) view).getText(), Toast.LENGTH_SHORT).show();

when lsit tiem is clicked add it to a array list like
           AddedItems.add(((TextView) view).getText());




          }


Once all click events are done 

before going to next activity 

b1.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

convert the string list to string array or whereevr in the activity you want 
// create string array  from array list

        myval= listPar.toArray(new String[AddedItems .size()]);

}
    });
